What are the reasons and solutions of thrust ball bearing damage?
Thrust ball bearing is mainly composed of three parts, namely seat washer, shaft washer and steel ball cage. Because of its structural characteristics, this kind of bearing can only bear axial load, but cannot bear radial load. And it is mostly used for crane hooks, jacks and parts with low speed such as water pump. We all know that equipment bearings should be properly selected and installed and pay attention to daily maintenance, otherwise it is easy to cause early damage to the bearings, and the same is true for thrust ball bearings. Next, the editor of Hengguan will introduce the causes and solutions of thrust ball bearing damage in detail through this article.
1. Causes of damage to thrust ball bearings
1). Improper installation
Some workers are accustomed to using brute force to directly hit the bearing surface when installing the bearing, causing deformation of the bearing assembly, and increased vibration during operation, resulting in bearing damage; or the bearing installation is skewed, causing the bearing clearance to fail to meet the standard, so the bearing is uneven when running, thereby aggravating bearing damage.
2). Poor lubrication
Poor lubrication is one of the reasons for the damage of thrust ball bearings. Bearings with insufficient lubrication will bear greater friction during operation, resulting in overheating and wear, resulting in bearing damage. There are many reasons for poor lubrication. Generally, there are improper selection of lubricating oil, lack of lubricating oil or insufficient filling, and deterioration of lubricating oil.
3). Bearing foreign body
If the bearing is not paid attention to when it is opened and installed, it will cause foreign matter to enter the internal space, or if the metal debris enters the internal space of the bearing due to inattentive maintenance after long-term operation, it will cause the bearing wear, abnormal vibration and cause excessive size, etc. In this case, the bearing will be damaged.
4). Overload fatigue
Long-term overload operation of thrust ball bearings usually causes damage. The reasons for overload fatigue are generally that the bearing selection does not match the equipment or working strength, overloaded operation over time, and untimely inspection and maintenance.
2 the solutions
1). Reasonable installation
When installing the thrust ball bearing, special tools should be used, and brute force knocking is prohibited. When the installation is completed, a measuring tool should be used to measure to ensure that the installation is in place.
2). Do a good job of lubricating
Select the lubricating oil that matches the model and fill it with sufficient amount. Regularly check the lubrication of the thrust ball bearing. When the grease is insufficient, it should be replenished in time. If the lubricating grease deteriorates, stop the equipment operation immediately and replace the bearing lubricating grease.
3). Do a good job in inspection and maintenance
Bearings should be stored before installation to prevent rust; during installation, ensure that the surrounding environment is clean, and check to prevent foreign objects from entering the bearings; bearings should be maintained and maintained during operation, and foreign objects should be cleaned in time to prevent metal debris from entering its interior space.
4). Prevent bearing overload
According to the equipment and working intensity, select the thrust ball bearing with matching specifications and parameters. The equipment should be given a certain rest time after working for a long time. The abnormality of the bearing should be checked and dealt with in time to prevent "sickness".
